Video on going in depth explaining how the smoke exhaust and pressurization fan system works and why it’s there kzfaq.info/get/bejne/q9xodbeTvbyZpYU.html

If my high school had been this modern and awesome I’d actually be excited to go to school.

Me getting so excited to see that He upload a one hour video

I was supposed to get a school like that but it never got passed sadly At least my current high school actually has many kinds of alarms. In the school itself it has a different model simplex and possibly Faraday horns, a red light on the wall in the assembly gym, and a gentex commander (Maybe version 1?) in the PE gym/Lunchroom, and finally an old Simplex horn in the choir room. The annex just has Simplex horn/strobes. The portables mostly have Spectralert advance horn/strobes, but the public speaking portable has a Spectralert classic. Also for emergency lighting, some lights in the front of the school and the annex have what looks like little red “O”s in them so I am guessing those lights stay on, the rest of the school just has Dual-lite twin heads and the “LBC lighting” I think it’s called. The portables have an old dual-lite and the public speaking portable has both the old dual-lite and a newer led one. However the science one has one on the side of the room and the one next to the door has no heads but somehow has a working battery.

I’ve been thinking about the horns seeming out of sync. Assuming the alarms actually are in sync, it is possible that it’s the speed of sound that is causing them to sound that way. Given the speed of sound is approximately 343 m/s, and the somewhat open concept of the school, we might just be hearing the delay it takes for sound to travel

Oh yeah the problem at 14:10 is supposedly very common with bg 12's and its dangerous since if someone pulled it it wouldn't set of the fire alarm. Of course for newer buildings smoke detectors will trip but for older buildings it's more of a hazard

nice video keep up the work love the vids the fan starting up scered me just like the last video when I knew it was going to start lol

Nic: "Hey jamie we should have one on this side of the rooftop, eh?" Jamie, somewhere behind the camera: *euraugh* 👹🗣

Fan sounds really cool when it turns on

A large school like this should really have a speaker system w/ voice, not a horn system. Horns should only be used in small systems.

When the fan started up it SCARD Me

Those fans sound so good when they startup

Love the fan startup

finally!! That campus looks so modern for 2015 standards, but very nice!! cant wait to see more

I enjoy watching your videos nic! I should be getting a rare fire alarm. We’ll two of them.

Love seeing those big fans operate! Are those fan motors controlled by some sort of VFD? And are they fed by a 600V three phase or another voltage?

Nice job I like to use walk test with horns and use smoke but you have to have a can of air to clear it or may go off again also it hard to find the spot place the magnet on smoke detector sometimes I also noticed detectors were not marked with there address on them wich is helpful in identifying with detector tripped as well for trouble shooting from Rich Owner of an Alarm Company.

Awesome video!

been waiting for this!

14:26 That pull Station has got an issue! I remember last years testing video there was an issue with another pull station in that school, is that the exact same pull station?

How often do the fire alarms get tested at your high school

I always thought that was just a 3030 display on the panel, but I never noticed the controls enabled led on the interface.

I knew it the switch inside the pull station didn’t go off.

I'll be shocked if you reply on a video this old, but what is the lighting system your school uses? The models of the switches would be appreciated, but I could work with a brand name. I like the design and the "networked" aspect of it.

I wish my high school looked like that lol. That school is really nice

Cool school I like the fire alarms

2:27 Do the doors also provide the first evacuation routes when they open?

Nice!

Good job keep up the good work

That is one fancy system dude I am helping to put one in at a strip mall in our local area

I thought the video was gonna be longer like 2 hours. But still great long video

im terrified of fans but those were cool

Is the footage of the exhaust fan going in both directions as it slows down after it gets shut off due to the camera or the fan itself? It looks like it spins clockwise for a few seconds, then counterclockwise for a few seconds at first, and then stays clockwise at the final stage when it finally stops.

The fans could be aerovent (Not sure about the concealed fan in the soffit)

What job do you do that you get to test fire alarms and veiw them (basicly work on them)

damn all the schools there are big i wish my school was like that

1:56 I wish this was a joke for April Fools, but I really want to know the full name of the school. I have been anxious to get your location for years.

I wonder why there is no protection on the fan inlet, you can just stick your arm inside?

4:18 THAT FREAKING SCARED ME!

This school is like a mall

Is that panel in the old portable electrical room networked to the main panel? And is the field house on that panel?

Nice one

I Would Not Use Ladder Lifts That's A Big No For Me Whoa I'm Really Scared Of Heights

3010 never seen that room in your schoool before is it just a pump room or like a boiler room?

You said your high school do you currently go there are you an alumnus? Thanks for the video.

Nice

How come they didn't sync this system? Also, no strobes?

Why is there a hood outside the exhaust fan room beside the door?

Seems like several of those pull stations didn't work how you'd expect. Seemed activated but requires you messing with it to trip. Seems like that shouldn't be possible

They should have installed scorpion smoke testers 62ft in the air

24:26 is the fire alarm system connected to the suppression system?

The start of that fan scared anyone else? Pretty cool video tho nic

It's gonna suck when a fire drill happens and it's winter cause all that cold air is going to be inside

1:08:15 When they silenced the alarms, I heard one out of sync still going for a second. Is that an outside horn/strobe?

an hour long?

4:10 Just doing some maintenance on this fan blade.. That fire alarm is probs just a drill anyway.. I'll continue working.. AHHHHH!!!

It is the exit door number of the door .

I have a BG-12 and it doesn't have problems with flicking the interior switch. That's all little weird. 15:38

I thought you shouldn't have a fan running when there's a fire.

Can you flim the elevators in this high school?

Isent there meant to be inc that goes on the kids hands who pull them?

true bro i am so excited😊😊

I feel like I would get lost in that school

29:03 Take Two.

Why does your High School doesn’t put the system in Walk Test when you guys test all of the pull stations and smoke detectors!

@NIC'S - SYSTEMS & ELECTRC this video is a bit longer so it explains a bit more

They need sync modules lol

Nice building but why ceiling are so high?

just imagein if you have to replace those high smoke detecters 58:04

Are you a Student? How did you get the keys to open doors?

Hi

But if there was a fire the last thing you would want to do is feed it fresh air?

Ahhhh the alarm is not in sync

At 47:23of the video what is the logo floating around for

How long

When is genetior test?

Why are there two control panels

Lol yea

Hay Nic

Thats so big😅😅😅

My mom is going to have to get the first 🥇 in the first 🥇

500:00:00

Police

That’s ilegal.
